LEVER- LOCKING DEVICE.

Be it known that I, CHARLESA. Biomonn,

ay citizen o1 the United States.- residing at Chicago, in the co'llntiy of Cook and State 0f Illinois, have invented a certain new and useful Iaiver-Iaicking Device, of which the following is a full, clear, and exact d`esrriptiou. reference 'being had tov the ac- (au'npanyilig dra wings, which .form u part off the specification. Y f- 'lheobject of my invention is to provide a locking' mechanism to'be applied to auton'lohiles of either the commercial :or pleasure type, which, when applied, makes itl possible elsewhere' ositively Alocked against loss by theft o1" ot icrwise. A v l A' further object of my`rinvent1on 1s to `provide, a locking lnechanis'ni which `willnfivt only lock the emergency brake lever but will -siniilltaneonsly, if desiredhoperate-.to disconnect the 'electric circuit wires and also to sliutofthe gasolene supply. f

Agrfurther object of Vmy invention is to proide alocking mechanism which w'll the breakin of the electric. circuit and irs xittng;` offthegasolene su p1y sol that y lts own out'of the garage `to sajety. V

Still' "Rather-Obiemmy inventiim is' to prvlideus'ucli an arrangement of parte in my" locking` mechanism as" to' preventfdismantl'ing' or tampering with the locking Raferriagm theaccompanyingfdrawings,

shown in''the drawings, 10 represents; an.v

emergency braker'lever ofV the'v automobile whichl is" fulcrumed at 11 andv carries the necessary lockimer` and brake mechanism for setting` the brakes and engaging' or disengaging the locking mechanism. The-sector l2 is composedof two parts, 13 and 14 formi'nga slot 15 wherein the lever 10 is guided in its movement. The sectoror quadrant pawl 1T engages.

f.To all 'whoml it 'm'.a-ji/ concern:

`has a series of notches 1G with which the To the bracket 18 is secured a flange 11) whieh carries n gasolene valve oi' the three way cork type made to close when the lever is at eitherend of the notched quadrant l2 whether in backward or 4extreme forward position. n i

ll'hen the emergency brake lever 10 is in position to release th'e brakes and permit the el|ga {enuent of clutch or other mechanism, the valve :04 is opened and the gasolene turned on. `'lh'nz valve 20 in the lin'e 21 leading `to the motor has :i piniong'enr 22 secured to the stein 2% so as to engage a quad rant ratchet :4 which may be cast on the lever l() or otherwise fnlcruinedon shaft 11 i the saine as the upper portion of the lever 10. A weh J5 covers this p in'ion 23 when the .whole device is assembled so. as to prevent its being dismantled ort'ampered with. My device also provnles for levercontrol of the This switch is host s'hnvn in'Figs. 2, 4 and`5 .4

It is assembled onthe cast web of the bracket i8 and when the lever 10 is at either end ofthe notched quadrant` f l2 in either extreme forward or backward" position, the electric circuit' to the motor is'- purpose any circuit' breaking switch of a siuiplevtypel comprising a" block 2601? hard.rubber or other suitable, non-conducting material,

On thisfblock 26 are secured' two' metalk terminal'plates 28 and 9.9. A fiber pinion gear member 30 having a metal pin 31 therein;

[serves to close the, switch` *bridging the circuit when passing between the parallel plates 28 and 2i). The fiber pinion member isv ivoted on a screw member 3Q flush-hondo at one end and slotted at the threaded lend to enga ewith the web of the quadrant bracket 18. tis'backed into piace whenmaki the assembly bynse of a screw driver.` his pin 32 alsoserves` as one of the helts'fe old the switch cover irpiaee" against: the web ofthe bracket I8 in such manner-ls'4 to en )rnpletely` gaar the ewtchassembl' against being tam er with or disinantl h 'l` he slotted end o the pin 32 is covered bv the wings 34'and 35 whichV are Vcast with the'lever 10.
